In either event appli cants have reference to a portion of the paths of travel of. the blank and finishing molds in which the blanks or parisons are transferred from the blank molds to the finishing molds. Also, where reference is made to charging position or station, it is intended to merely identify a portion of the path of travel of the blank molds wherein directions at as it travels thro tarmac Y Y said molds.

I Referring particularly to Figs. 1, 2 and 3,

the machine comprises a blank mold carriage or table 30 and a finishing mold carriage or table 31 mounted side by side on a wheeled base or truck 32 movable on rails 33 toward and from a gathering tank 34: in which a continuous supply of molten glass is maintained:

The blank mold carriage 30 is mounted for rotation about a stationary hollow column or standard 36 bolted to a base plate 37 which in turn is bolted to the platform 32. A gear 38 fixed to the carriage 30, intermeshes with a gear 39 of mual diameter on the finishing mold carriage 31, so that the carriages or mold tables are rotated in synchronism in opposite the same angular speed. The carriages may be driven by a motor 40 (Fig. I) connected thereto through suitable gearing (not shown) The finishing mold carriage 31 (Fig. 3) is mounted for rotation about a central hollow stationary column or standard ll which is secured to a base plate 42 adjustabl .orted on the ully set forth.

Referring to Figs. 1 and 2, an annular series supplatiiorm 32, as hereinafter of dip frames 43 are mounted on the blank mold carria e for swinging movement about horizontal pivots 414i. Each dip frame carries a sectional blank mold 45, a sectional neck mold to and operating mechanism therefor. During the rotation of the mold carriage, each dip frame as it approaches the gathering tank 34 is tilted upward, as shown at the left hand side of Fig. 2, to permit the blank mold to c ear the rim of the tank, is then tilted downward to bring the mold in contact with the body of glass in the tank for gathering a charge by suction, after the gather is tilted u ward to again clear the rim of the tank, alter which it is again tilted downward to bring the mold to its normal level which is maintained thpoughout the greater portion of its travel. The dip fr held in the position shown at the right hand side oil Fig. 2, with the mold axis vertical, exceptwhen tilted upward to clear the rim of the tank.

The position of the dip frame relative to the mold carriage is controlled by a earn it? (Figs. 2 and 6) on which runs a roll 48 on the dip frame. Q The cam 47 comprises a tired section 47 for tilting the frame upward dur- A ing its travel through are a I the rim oi the tank, an adjustable section 4?? controlling the dip or the mold into the glass h are 3, an adjustable section 47 for lifting the mold out of dip dur- (Fig. 3) to clear .ing its travel through are c, and an adjustable section t? for again lowering the mold.

The cam section 4%? is adjustable circumilerentially of the mold carriage by mecha,

nism including a hand wheel 49 on a worm shaft 50 carrying a wheel 51 running in mesh with a worm wheel 52 on the lower end of a vertical shaft 53. A pinion 54 on the upper end of said shaft runs in mesh with a rack 55 secured to the adjustable cam section 47. By rotating the hand wheel 49, the cam section 47 may be adjusted either toward or from cam sur ace for all relative adjustments of the cam sections. v

The cam section 47 is adjustable toward and from the section 47 by mechanism substantially like that just described including a shaft 56 on which is a hand wheel (not shown), said shaft carrying a worm 57 meshing with a worm wheel 58 on a shaft which carries a gear 59 engaging a rack on the cam section 47. By adjusting the cam section 47', the point at which the mold is brought in dip may be adjusted independently of the point at which it is l fted out of dip. The length of time the mold is in dip is repre-" sented by the are e of variable length.

The cam section 47 d is adjustable circumferentially by means of a hand wheel 60 on a shaft carrying a worm 61 running in mesh with a worm wheel 62 on a shaft wh ch carries a pinion 63 meshing with a rack 64 on the cam section 47 The blank mold 45 comprises the usual partible hinged sections. .The opening and closlng movements are controlled by a cam 65 (Fig. 2) on which runs a cam roll 66 on a slide 67 movable radially of the machine on guide rods 68 mounted onthe dip frame. The usual operating connections 69 are provided between the slide 67 and the mold 45..

The cam 65 comprises a section 65 (Figs. 2 and 10 to 12) which is rotatively adjustable about the axis of the blank mold carriage. The mechanism for efiecting such adj ustment comprises a pinion 70 running in mesh with a rack 71 on the "cam section 65, said pinion being secured to a vertical shaft 7 2 j ournaled' in bearing blocks 73 mounted in the hollow standard 36. A worm wheel 74 on the lower end of the shaft 72 runs in mesh with a worm 75 on a shaft 76 which carries a hand wheel (not shown). By means of the adjusting mechanism just described, the cam section 65 which controls the opening of the blank mold may be rotatively adjusted to adjustably vary the time at which the blank mold is opened.

' The adjustable cam section 65 (Fig. 11A) is approximately the form of a circular disk concentric with the standard 36 through the major portion of its circumference and is formed on its under surface with vertical cam walls 77 to provide a channel for the cam roll 66. This channel commences at the radial line 78 (Fig. 10) and curves inwardly toward the center of the mold carriage to provide a mold opening section, the extent of which is indicated by the arc 79 (Fig. 10)

At the radial line '80 the depth of the cam wall 77 is reduced, providing a comparatively narrow extension 81 (Fig. 10B) concentric with the axis of the mold carriage. The stationary cam section which underlies the adj ustable section is formed with a vertical cam wall 82 which, as shown in Fig. 10B, is provided with an extension 83 underlying the section81. The sections 81 and 83 are telescopically arranged to provide an unbroken cam surface for the roll 66 in all positions of adjustment. 'The cam wall 82 comprises a blank mold closing portion 84 extending from the radial'line 85 to the radial line 86 at -which the cam groove terminates.

With the parts adjusted as shown'in Fig. 10, the opening movement of the blank mold will commence when the cam roll 66 reaches the radial line 78 and will be completed when said roll reaches the line 80. The mold then remains open during its travel through an are 87 extending from the radial line 80 to the line 85. The closing movement then commences and is completed when the cam roll reaches the radius '86. The range of the blank closing movement is represented by the are 88. a

When it is desired to effect the opening of the blank mold at a later period, the cam sectidn 65 may be adjusted in a counterclockwise direction and thereby bring the cam opening section to the dotted line position (Fig. 10) The opening of the mold will then be effected during the travel of the cam roll from the radial line 89 to the line 90. The blank mold will then remain open during its travel through "the are 91 extending between the radii and 85. It will be noted that the time at which the blank mold is closed is not affected by adjustment of the cam. The blank moldr-emains closed during its travel through an are 92 when the cam is in the full line position (Fig. 10). By adjustment of the cam, the'blank' mold may be held closed during the additional period represented by the are 93 extending between the radii 78 and 89:

The means for applying suction to the blank mold for gathering a charge of glass will be understood by reference to Figs. 2, 2B and 7 vacuum and air drum 94 surrounding the column 36, provides a chamber 95 divided into separate compartments by means of radial partitions 96, there being one compartment for each dip head. An air and vacuum line 97 extends from each compartment 95 to the corresponding mold. A valve 98 in the line 97 controls the periods of time intervals during which air pressure and vacuum respectively are applied to the mold.

Overlying the drum 94 is a stationary plate I '99 held against the drum by springs 100.

charge of vacuum pipe 101 connected to the plate 99, communicates with an arc-shaped recess or channel 102 formed in the lower face of the plate 99. In each compartment of the drum is a port opening 103 extending through the upper wall of the compartment in position to register with the channel 102 as such compartment travelsebeneath said channel during the rotation of the drum.

The vacuum pipe 101 is-connected to a constant source of vacuum and it will be seen that as a port 103 passes beneath the channel 102, communication is established from the vacuum pipe to the corresponding drum compartment 95, so that the air is exhausted therefrom. After the air has been exhausted the corresponding 7 om a compartment 95, valve 98 is opened by means of a cam 104, so that suction is applied to the mold and a glass is thereby drawn into the mold in a Well known manner; The valve 98 then closes. After the mold has received its charge and is lifted from the pool, a knife plate 105 operates as hereinafter explained to sever the glass and close the bottom end of the blank mold. The usual plung er tip is then withdrawn (as hereinafter constant source of air drum rotates.

. the port 103 in said compartment has passed noted) and air under pressure applied for compacting the glass in the mold. For this purpose, air under pressure is supplied through a pipe 106 ig. 7) connected to a connected to the plate 99 and communicates through an opening in the plate with an armate channel 107 in the lower surface of said plate. Port openings 108 extending through the upper Wall of the drum 91 are brought into register with the channel 107 as the It will thus be seen that each drum compartment 95 is brought into communication with the air pressure after beyond the channel 102 in the vacuum line so that communication with the vacuum line has been cut 0E. The valve 98 is opened by means of a cam 109 to admit air through the line 97 to the mold. e glass which the valve 98 closes, cutting ofi the air pressure.

Each ofthe cams 104 and 109 comprises a multiplicity of cam sections, as shown in detail in F igs. 8 and 9. Each cam section comprises a head 110 formed with a lower horizontal cam surface 111. A stem 112 integral with the head 110 extends upward through a guide plate 113. A latch 114 connected to the stem 112 by a. pivot 115, is provided with a notch or recess to engage a holding rib 116 on the guide plate 113. The cam section may thus be held in its elevated or inoperative position, or may be lowered by disengaging the latch. It may be locked in its lowered position by engaging a shoulcured by bolts pressure. This pipe is ora-Mo der 117 on the latch beneath the rib 116. The guide plate 113 is removably attached to an angle bracket 118 which is removably se- 119 to a cam supporting plate 120 which, as shown in Fig. 2, is formed integral with a hub or. sleeve 121 surrounding the column 36. By adjusting the individual cam sections, the cam 104 may be adjusted to operate the valve 98 for supplying vacuum to the mold at any desired point and for cutting ofi the vacuum at any point independently of the time of valve opening. In like manner, the time at which the air pressure is admitted to the blank mold and the time at which it is out Oh may be independently adjusted by adjusting the individual sections of the cam 109.

The hlife plate 105 (Fig. 2) is carried on a bell crank lever 125 which has a pivotal connection 126 with a sleeve 12? mounted on a hollow shaft 128 which forms part of'the dip frame. W'hen the mold is lifted after receiving its charge, the lie plate 105 operates to sever the glass. The operation of the bite is under the control of a cam track 129 (Figs. 2A and 6). Fixed to the lower end of the shaft 128 is a rock arm 130 carrying a roll 131 which runs in the track 129 for rotating the sleeve 1271' and thereby swinging the knife plifte across the bottom of the mold to sever the glass. The ife plate is then held against the bottom of the mold, forming a closure therefor during the blowing of a parison in the mold as heretofore described. An adjusting cam 1352 mounted'on the shaft 128 is rota-tivelyadjustable thereon and is formed with a cam slot to engage the lower end of the bell crank lever 125. The cam slot is so shaped that rotative adjustment of the cam will swing the bell crank lever onits fulcrum and thereby adjust the plate 105 toward or from the mold. If desired, a separate mite may be used for severing the glass at the bottom ofthe mold, as, for example, a stationary brife such as shown in the British patent to ONeill, Number 315,154, July 11,1929. The plate 105 would then serve simply as a closure for the mold bottom. Y

' The plun er133 (Fig. 27) with the plunge er tip for unning an initialblow opening in the parison, is actuated by a swinging arm .133 pivotally connected to a standard 13d and having operating connections 133 with the plunger. When the arm 133 is swung up, the plunger is held imits lowered operative position by a cam 133 on the arm 133. After the mold has received-its charge, the arm 133 is swung down by means of a cam 135 (Figs.

1 and 23) to cause the plunger to be with- I on a bracket 138 having a stationary mounting. A pinion 139 on the shaft 137 enga es a rack 140 attached to the cam plate 135. fter an adjustment of the cam the hand wheel 136 is lockedby a clamping screw 141. The

cam plate 135 has a slot and pin connection 142 with a cam plate 143-formed with a cam track 144 which serves to hold the plunger in its withdrawn position. t

As the blank mold with the parison therein approaches the parison transfer position, it is opened, leaving the parison supported v in the neck mold 46. The neck mold with the 147 on a neck mold carrying frame 148 mount-.

parison therein is projected radially outward .for the transfer by means of a cam 145 (Figs.

1, 2, 20, 21, 24 and A cam roll 146 running on the cam 145 is mounted on a bracket ed to slide .radiallyof the machine on guides 149.. The cam plate 145 is adjustable about the axis of the blank mold carriage by means.

of a hand wheel 15Q (Figs. 1 and 21) connected to a pinion 151 engaging a rack 152 attached to the cam plate 145.

The neck mold is opened by means of the arm 133 operating through a plunger 153 which carries at its lower end a wedge for spreading the neck mold arms in a well known manner, as shown, for example, in the British Patent Number 315,154 above-mentioned.

' fer, the arm 133 is moved downward sufliopening or cracking the-neck mold just before the corresponding finishing mold closes ciently to engage the plunger 153 and move" it downward a short distance for slightly about-the parison, thereby preventing shearing or distorting of the parison due to any slight relative movement ofthe neck mold and finishing mold at the moment of transfer. After the parison is enclosed in the finishing mold, the plunger 153 is moved downward 'sufliciently to completely open the neck mold.

The mold is opened and closed by means of a cam with which engages a roll 17 0 carried on a slide block 171 mounted to slide radiallyof the mold carriage in guides 172. Links 173 connect the slide 171 with the levers 168. The guides 172 are supported on a plate 176 which is integral with the mold carrying yoke 167. The plate .176 overlies and is supported ona' plate 174 which is adjustably mounted on the mold carriage. Adjusting bolts 175 (Fig.

13) permit adjustment of the plate 174 about the axis of the carriage. The plate 176 which carries the mold is adjustable radially of the machine by means of an adjusting screw 177v rotatably mounted in a bracket 178 on the plate 174, said'screw having a threaded connection with a lug 179 on the plate 17 6. By rotating the screw 17 7, the slide plate 176 may be adjusted radially of the machine. This, togetherwith the means 175 for lateral-adustment, permits the mold to be adjusted horizontally in any direction so that it may be brought into accurate alignment withthe neck mold at the time of transfer.

' The cam roll 170 (Fig. 14) is carried on a block 180 which is slidably'mounted on the plate 171 to permit relative adjustment of said block and plate in a direction radial to the mold carriage. Set screws 181 hold the parts in their adjusted position. By loosening the set screws, the slide plate 171 is free for adjustment radially of the mold carriage while the guide roll 17 Ois held by-it's cam. A bottom plate 182 (see Fig. 5) for the finishing mol is carried on a swinging frame 183 having a pivotal connection 184 with the g plate 176 which, supports the blank mold.

Each said line includes a pipe 202 extending from the chamber 200 to a valve 203, apipe 204 extending from the valve to the hollow pivot 192, and a pipe 205 extending from said pivot to the blowing head. The -valve203 is opened and held 0 en during a predetermined arc of travel 0 the finishing'mold .bya cam 206 comprisin .a multiplicity of adjustable sections whic may be of the construction shown in Figs. 8 and 9. The cam, as shown in Fig.

15, extends through an arc of substantially, more than 180 degrees,

the cam sections may be made to hold the valve 203 open and supply air pressure to the finishing'mold during its travel through any desired portion of said are.

The cam for opening and closing the finishmolds (see Figs. 3 and 17 to 19) comprises a fixedcam section 207 and an adjustable section 207. formed with a rack 208 engaged by a pinion 209 on the hearings in ocks 211 in the center column '41 of the carria e. A worm wheel 212 on the lower end 0 the shaft engages a worm 213 on a shaft 214 carrying a hand crank 2115 (see Fig. 1). By rotating the crank 215, the cam section 207 Q is adjusted about the axis of the mold carriage to adjustably vary the point at .which the finishing mold is opened.

The mm 193 for operating the blowing head comprises an adjustable section 193 i I which is bolted to the adjustable section 207 of the finishing mold-cam and is adjustable. therewith.

The finishing mold carriage 31 and its supporting column 41 are adjustable bodily as a unit in a horizontal direction about the axis of the blank mold carriage, as will be understood by reference to Figs. 1, 3 and 26. For the purpose of such adjustment, the base 42 is formed on its under surface with ribs 216 which are slidable in arc-shaped grooves 217 in the platform 32, said grooves being concentric with the blank mold carriafge. slots 219 in the plate42 and have a threaded connection with the platform 32, thus preacement of the base plate 12. The adjustment is efi'ected by means of a hand crank 220 on a shaft 221 .carrying a worm 222 running in mesh with rack-teeth 223. on the base plate 42.

By means of the adjusting mechanism just described, the finishin mold carriage may be adjustably moved orward or backward around the axis of the to correspond to any adjustment of the neck mold projecting cam 1 15. The finishing molds may thus be caused to close around .the parison in synchronism with the transfer movements of the neck mold, for any adjustwill correspondingly lBolts 218 extend through arc-shaped blank mold carriage ment of the transfer station about the axis of the blank mold carriage.

It will be noted that any ltstment of the finishing mold carriage about J the axis of the blank mold carriage in the manner above described, 39 to roll on the gear 38, or rotative position of the will cause the gear so that the angular finishing mold carto the blank mold carriage is changed 1n a manner which would prevent proper registry of the neck mold "and finishing mold at the time of transfer. To com pensate for this, there is provided means for translatory ad rotatively adjusting the finishing mold car riage about its axis. Such is shown in Figs. 3 and 4 hand wheel 224 (Fig. 4:) journaled in bearings 225 adjusting means on the hub of the gear wheel 39. The worm meshes with a worm wheel 226 which is secured to the hub of the mold carriage. B rotation of-th'e hand wheel 224, the mol carriage may be adjustably rotated.

Modifications may be. resorted to within,
